如何将空格分隔的变量传递到bat 文件中？

我想将一个空格分隔的变量传递到批处理文件中，例如：

c:\applications\mi_pocess.bat A1 1AA

当我跑步时echo %1 in mi_process它返回A1

我将如何去认识它A1 1AA是一个单一的字符串？

我尝试过在外部软件中将其用双引号括起来，例如

c:\applications\mi_pocess.bat + chr$(34) + A1 1AA + Chr$(34)

and echo %1现在返回"A1 1AA"（我不想在变量中使用引号）

我相信你知道%1, %2.bat 中的 等表示在命令行上传递给 .bat 的编号参数。

如果您将它们用作%~1, %~2等等。如果存在的话，所有周围的引号都会被自动删除。

考虑一下这个space-in-args.bat供测试用：

@echo off
echo.  %1
echo.    (original first argument echo'd)
echo.
echo. "%1"
echo.    (original first argument with additional surrounding quotes)
echo.
echo.  %~1
echo.    (use %%~1 instead of %%1 to remove surrounding quotes, should there be)
echo.
echo. "%~1"
echo.    (we better use "%%~1" instead of "%%1" in this case:
echo.      1. ensure, that argument is quoted when used inside the batch;
echo.      2. avoid quote doubling should the user have already passed quotes.
echo.

Run it:

space-in-args.bat "a b c d e"

输出是：

 "a b c d e"
     (original first argument echo'd)

""a b c d e""
     (original first argument with additional surrounding quotes)

  a b c d e
     (using %~1 instead of %1 removes surrounding quotes, should there be some)

 "a b c d e"
     (we better use "%~1" instead of "%1" in this case:
       1. ensure, that argument is quoted when used inside the batch;
       2. avoid quote doubling should the user have already passed quotes.
